While traveling in the UK Dad would spot a Manx License plate somewhere and leave a note on the windshield saying "hi" Random and kind of weird but I hope it would have made a few people smile.

I’ll never forget, during one of many fire company related classes we were discussing ‘Tot Finder’ stickers. You know, the ones that you see in Windows so that firefighters know there is a child in that room in case of emergency. They’re good and bad. People know there is a child in that room, at the same time people know there is a child in that room.
